IoBind uses meta-programming and policies to
create readers and writers for complex objects at
compile time. In other words, it is a code factory

process, and it will generate the corresponding
code: STL containers, uBLAS matrices, etc.

TinyXml is a simple, small, and minimal C++ XML parser that
can be easily integrated into other programs. It reads XML and
